Expert Reply:

To charge the 4 battery bank on your 2004 Discovery 39 I recommend using the NOCO GENPRO On-Board Battery Charger - AC to DC - Waterproof - 4 Bank - 12V - 40 Amp # NOC84FR, which will charge batteries rated for up to 230 amp hours. You can also add the NOCO AC Port Plug with Extension Cord - 16" Long # 329-GCP1 to this setup to allow you to plug an extension directly into the coach since this setup will likely be stored in a cargo hold, out of the elements.

For your engine batteries, the NOCO GEN On-Board Battery Charger - AC to DC - Waterproof - 2 Bank - 12V - 10 Amp # NOC34FR is what I recommend. These NOCO Genius chargers analyze the battery condition to provide a customized charge, so they'll never be over-charged; additionally these have a built-in battery desulfator that restores lost battery capacity, so these units do 2 jobs at once.

I've linked some review videos of these parts for you to have a look at, as well.
